OEM High-precision optical lens: Plano Concave Lens
The Plano Concave Lens has a flat surface on one side and a concave surface on the other, characterized by its negative focal length. It is ideal for applications such as image reduction, light diffusion, and beam expansion. When combined with other lenses, it significantly enhances the flexibility of optical system design, particularly for extending working distances and expanding LD beams.
The lenses are standardly uncoated but can be customized with anti-reflection coatings or other specialized coatings upon request.
